IMPROVEMENT IN SCISSORS.

Specification forming part of Letters Patent No. 44,556, dated October 4, 1864.

To @ZZ whom t 71mg concern.-

Be it known that I, FRANcIs G. SANEORN, of Andover, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Scissors; and I do hereby declare th at thefollowin gis a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Which- Figure l is a representation of an ordinary scissors, with my improvements attached thereto. Fig. 2 is a detailed sectional view of the parts added to the scissors in Fig. 1.

Similar letters of reference indicate like parts. v

My invention is designed to combine the ordinary scissors and the button-hole scissors in one implement, in such a manner as that each shall be independent ot' the other in their positions, and the efciency ot' each be as complete as though they were separate implements.

Fig. l shows a scissors with my improvement, which consists in attaching` to the inner i'aees of their shanks the cutter A and metallic bed D, for the purpose of cutting buttonlioles and similar uses, it being only necessary to change the form of the cutter, it' any cut other than that necessary for a buttonhole is desired. A punch may also be substituted for a simple cutting-edge, it such a tool is desired, instead ot' a cutter. The cutting-edge is to be cast upon one of the shanks, andthe bed issecnred upon the opposin g shank by slipping a sleeve, a, upon the other shank, and bringing its edges together, or nearly together, and uniting them to the inner face ot' the bed D by soldering or brazing. A screw-thread is tapped through the opposite side of the sleeve, in which is inserted a setscrew, B, by means of Which Iam enabled to adjust the bed. D toany position, according to the length ot' the cut desired. It' the eut is to be the Whole length of the cutting-edge, the bed is to be brought to coincide with its ends, but if the cut is to be of less length, the bed D is to be set to the right or lett, so that the bed will present only a corresponding length of its surface to the cutting-edge.

The shanks ot' the scissors or shears are to be formed, as shown, so as to afford room in the space C, between the joints of the blades and the cutting-edge, to receive the edge ot` the cloth or other material.

Any scissors now in use can be tted with niy improvement by soldering or hanging the cutting-edge to one of their shanks, and the bed, which is to be of any soft metal suitable for this purpose, can be simply brazed or soldered, also, to the other shank.

The set-screw, when one is used, may be in any part ot' the sleeve, and more than one screw can be used t'or this purpose. It is not necessary to use a circular sleeve whereby to attach the bed to the scissors, as any equivalent method--sucl1, for instance, as a bracket or a sleeve, open at one side. or ot' a skeleton formmay be employed. The bed may be fastened to the sleeve or bracketpiece by means of screws or rivets instead of by braz- 1n l claim as new and desire to secure by Letters Patent- Attaehing a cutting-edge and bed to the shanks of scissors, in the manner substantially as described.
